TO ALL WHOM IT MAY CONCERN:

Be it known that I, DAVID A. Limits, of Cincinnati, in the county oi"Hamilton, and S Ohio have invented acertain new and useful Method ofExpressing Fluids from Solids; and I do.hereby declare that thefollowing is a. full, clear, and exact description of the constructionand operation o'fthe same, reference being bad to the annexed drawings,making part of this specification, in which- Figure 1- is a. perspectiveview of an apparatus illustrating my method.

Figure 2 is a longitudinal sectional view of the same apparatus. v

My invention consistsoi' a method of expressing fluids from solids, bymeans of a vertical trunk or tube, pcrforated with numerous holes, andprovided with a cloth or canvas lining throughout its entire length,into which the substance from which the fluid is to be expressed isintroduced, until the pipe is full, or nearly so, when the weight of thematerial to be acted upon will force the fluid through the pores of thelining and the perforations in the tube, while the solid remains in thetrunk, andjs discharged through the bottom.

This invention is especially adapted to the separation of oleine fromstearine, but it is obvious that it may be applied to other analogouspurposes.

To enable others to use my method, I \vill dcscribe the form in which Ihave embodied it for the expression oi' oil framing], and which form isshown in the drawings.-

Jl is a tube ortrunk, from thirty to fifty feet in length, placed in avertical or nearly vertical position; It may be made in a single piece,or it may be madein sections, connected by flanges, asat B, whichflanges may also serve as ledges or'shelves, to receive the expresscdfluid at different elevations; This tube may be made of wood or metal,and perforated, or may be made of woven-wire cloth. 7 It may also becylindrical, square, or

of any convenient form in cross-section. Near the lower end, and belowthe perforations, is a door or valve, 0.

At thetop is a ring, D, to which is attached a bag or lining, E Thislining may also be made in sections,

attached to the sides of the tube, or to the flanges, when the pipe ismade of more than one piece. The ring D is provided with a flange-by\vhich'it rests upon the trunk. I

Into tllebng or lining the lard or other material to be acted upon isintroduced, and, if deemed necessary, it may be kept in.a funnel-shaped'or other receptacle, above-the tube, so asto be self-feeding. Theweight of the super-incumbent lard forcesthe oleine through the pores ofthe lining and perforations of the tube, while the'stearine graduallydescends, and is discharged throughthe gate 0, at the bottom. I

It is obvious that the details .of'the construction of this apparatusmay-be considerably varied without departing from the principle of myinvention. The tube need notbe perforated throughout its'entire length,and the perforated portion may be either a. continuation in the line ofthe upper part,ns shown, or maybe placed at any convenient angle to it.-Instead of thecloth or canvas lining, the material to be acted upon maybe enclosed in bags and thrown into the tube.

What I claim as new herein, and desire to secure by Letters Pntent,.is--

1. The method of expressing fluids from solids, by the pressure of thematerial to be acted upon, in a' tube or trunk, substantially asdescribed. I v

2. The perforated trupk, in combination with the cloth or canvas lining,substantially as and 'for the purposes describedg I g 3. Thecombination'of the perforated trunk with the discharge-valve c,substantiallyasand for the purposes described. i p
